We look at the division of 90441979 by 2 
Let's see how many times 2 fits into 90441979.

Going ahead to step 1:
2 goes into 9 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 1 after subtracting 8 from 9.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Let's proceed to step 2:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 10 from 10 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Step 3:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 452.0
Subtracting 4 from 4 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Step 4:
When dividing 4 by 2, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 4522.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

On to step 5:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 45220.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Moving on to step 6:
19 divided by 2 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 452209.0
If we take 18 away from 19, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Moving on to step 7:
When dividing 17 by 2, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 4522098.0
If we take 16 away from 17, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Moving on to step 8:
2 goes into 19 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 45220989.0
Subtract 18 from 19 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45220989.5
Subtract 10 from 10 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 45220989.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 45220989.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 45220989.5, with a leftover of 0.0.
